WILLIAM l. KNOX, OF OWEG'O, NEW Y Application filed May 21, 1927. Serial Ito. 193,370.

My invention pertains to .a device for marking parts of shoes for the purpose of assisting and expediting the process of matching or lapping the parts torv sewing,

e and for other purposes.

It has been the usual practice in the'past to so mark the shoe parts by hand with the use of a form and punch. Such a process is slow and tedious and it isthe purpose of lo my invention to provide a device by means of which a complete set of parts fora given shoe may be simultaneously and quicklymarked. I

A further object of my invention is to pro-:-

tevide such a device with pattern members which may be made up for any" desired marking and q uickl inserted or removed from the marking evice.

A still further object is to provide a deas vice which has a relatively fixed or stationary guide pattern for receiving the parts to be marked and a movable punching pattern cooperating with said guide pattern, whereby all the arts may be punch marked sih multaneously.

An important feature of my invention lies in the means for readily removing both the guide pattern and the punching pattern, whereby they may be replaced in the device with others of like character arranged with a difierent punching design.

@ther objects and advantages in details of construction and operation will be apparent as the description proceeds, reference now being had to the figures of the drawings wherein like reference numerals indieate like parts. i

In preparing pieces of leather or other material for assembly into shoe form, it is the practice to first out such piece to size and shape according to the shoe to be made and then to mark with a punch aroundcertain edges of the cut pieces, the point to which the same will overlap with and be secured to its component part. Obviously, if several of such shoe parts can be so punch marked at one time accurately, a great savmg of time and labor is accomplished. To this end, I have provided an improved punch marking device, possessing many advantages and which will now be described.

There is provided a base member 1v preferably of heavy steel and which is provided on its top surface with a recessv2 within which is adapted to be placed a guide pattern 3. This guide pattern is preferably formed of heavy cardboard or other suitable material and when placed within the recess 2 has its uppersurface lying slightly below the upper surface of the base member 1. Means are provided for retaining the guide pattern 3 in such position comprising screws 4 placed about the edges of the recess 1, and between the heads of these screws 4 and the guide pattern 3, are washers 5 having one edge cut away as at 6 whereby said washers may be turned upon loosening of the screws 4 to bring such cut away edge intoalignment with the edge of the guide pattern 3 permitting the same to be removed or inserted within the recess 2. The edges of the base member 1 are recessed adjacent j the screws 4c as at 7 to permit such turning of the Washers 5. As shown in Figure 1, the washers 5 have been turned so that their uncut edges overlie the guide pattern 3 and with the .screws 4 tightened in such position, such guide is securely held within the recess 2. Guide pins are provided in the base member 1, such pins passing through suitable eyeleted openings in the guide pattern 3, whereby such pattern is always accurately positioned within thehase member It,

*l lhis guide pattern 8 is provided with a plurality of guide pins or studs 9 projecting siightiy above the surface ofthe pattern and arranged in the proper position and to r shoe parts 16 which are placed. on n 3, such as is shown in dottd hues in .E=Ilgll1 l. Uhvrously Mill wit

. ation.

given size and shape of a part to be marked, the guide pins 9 are arranged to accommodate such shape or design of art. It will be understood that any num er of guide patterns may be made up for as many dif ferent designs, shapes or sizes of shoe parts to be marked as desired or necessary, and all of such guide patterns are made the same size and adapted to be received within the base member 1 for the marking oper- Figure 8 illustrates one method of securing these guide pins to thepattern 3 and includes a headed stud which may be staked or otherwise crimped or riveted into the under surface of the guide pattern as at .11.

The base member 1 is provided at its rear edge with two upstanding bearings 12 through which passes a shaft 13 forming a pivot for the swinging top plate 14. This top plate is provided along one edgefwith integral bearings'15 ,surroundingthe shaft 13 and keyed thereto as at 16. A coil spring 17 is anchored at its ends in the base plate 1 as at 18, is coiled about the shaft 13 and has a portion thereof secured as by staples or other suitable means 19 to the u per side of the top piece 14, the tension of t e spring 17 normally exerting its tension to raise such top piece upwardly and out of engagement with the base plate 1. A stop lug 20 is secured to one end of the shaft 13 in position to engage with the rear edge of the base plate 1 and thus limit the upward movement of the top piece 14. This top piece 14 is provided on its outer surface with reinforcing ribs 21, one of which curves away from the front edge of the top piece 14 as at 22 to provide a finger space for the operator along the edge of the top piece whereby the same may be rocked downwardly on its pivot.

The under surface of the top piece 14 is ptcvided with a recess 23 to receive a punchpattern 24 of substantiallythe same size and shape as the guide pattern 3. This punch pattern 24 is relnovably secured within the recess 23 in the same manner as the guide pattern 3 is secured within the base member 1, that is by means of screws 25 and eccentric Washers 26. Guide pins 27 are also provided on the under surface of the I top piece 14 for accurately positioning the punch pattern 24.

Secured to the punch pattern 24 are the punch members 28, pointed at their projecting ends and as shown-in Figure 7 comprisingthe pin 28 driven or otherwise rigidly secured within a plug 29 which plug is staked or otherwise secured as at 30 to the punch pattern 24. I

hese punches or markers 28 are so arranged on the pattern 24 as to engage with and stab the shoe parts 10 arranged on the guide pattern 3, at precisely the desired points. The arrangement of the punches 28 is of course predetermined for a given shoe part to be marked and will of course be a punch pattern 24 corresponding to the guide pattern 3 for a given set of parts to be marked.

The operation of my improved punch marker is as follows :Assuming that it is desired to punch mark'a certain quantity of shoe parts of a given size and design, the guide and punch patterns 3 and 24, previously prepared for that'particular size and design of shoe parts, are placed within the recesses 2 and 23 respectively of the base member l and top piece 14 and secured therein by means of the eccentric Washers 5 and 26. The operator now lays a complete set of the parts to be marked on the guide pattern 3 in cooperation with the guide pins 9. The top piece 14 is now swung downwardly on its pivot to the position shown in Figure 2 at which operation the punch members 28, punch the openings 31 (see Figure 6) in the parts 10 in exactly the desired position with respect to the edges of said parts. In this manner, a complete set of shoe parts may be punched simultaneously and accurately thus eliminating the necessity of punching each piece separately and by a single hand punch. f

After the particular size and design of shoe parts have been thus marked and it is desired to similarly mark another set of a different size or shape, the guide and punch patterns 3 and 24 are removed from the device andother patterns inserted in their place corresponding to the parts now tobe marked and the operation repeated.

It is frequently desirable on certaingrades of shoes to provide parts thereof with fancy stitching or other decorative work. In such case, it is desirable to mark on the shoe parts to be so decorated a guide line which the decorator can follow. The punch. marks above described and used for lapping urposes are not suitable for this type of marking and for this purposes, there may be provided a modified form of pattern to go in the top piece 14 of the marking device. Such a. modified form of pattern is illustrated in Figure 5 wherein the pattern is indicated at 32 and mounted thereon as by rivets or other suitable means 33 is a marking tool provided with an upstanding marking edge 34 of a design corresponding to the guide pattern in the lower or base member 1 which guide pattern has of course been laid out to receive a given size and shape of shoe part to be marked. In the use of this form of marker, the marking edge 34 is preferably painted or coated with a color substance which will leave a colored line or mark on the shoe part corresponding to the marking edge 34.

In using this type of marker, the marking edge 34 may include extensions or independent portions of the same character for the purpose of placing the lap marks on the material at the same time the guide marks for decorative purposes are placed thereon. In such event, it is unnecessary to use the punch type of marker for the lap markings for in this manner both the decorative markings and lap markings can be simultaneously made on the shoe parts. This form of marker, however, is to be used preferably only when decorative marking is to be made, for the punch form of markings is much easier inasmuch as the marker does not have to be painted or coated with a color substance before each marking operation.

Of course, many changes may be made in details of construct-ion and arrangement of parts without departing from the spirit of my invention. I do not limit myself, therefore. to the exact form shown and described other than by the appended claims.

I claim 1. A marking device for shoe partsand the like, comprising a base member, a member movable relatively thereto and engageable therewith, a guide pattern on said base for receiving the parts to be,marked, and a marking pattern on said movable member carrying means for marking said parts while on said guide pattern, said patterns being readily removable as units from'said members.
